In some embodiments, steps S201 and S203 are optional, and one or more of these steps may be omitted or replaced in different embodiments.

In some embodiments, reference may be made to other optional implementations recorded before or after the description corresponding to FIG. 2 .

In some embodiments, when downlink control information (e.g., MC-DCI) for scheduling multiple cells is introduced, the terminal's processing capability for DCI also needs to be considered for MC-DCI. The format of MC-DCI includes at least one of the following: DCI format 0_3, DCI format 1_3.

In some embodiments, a terminal may receive and process unicast DCI, where unicast DCI refers to DCI sent by a network device to a terminal in a unicast manner, and unicast DCI may include legacy DCI, such as DCI for scheduling a single cell, including but not limited to at least one of the following: DCI format 0_0, DCI format 0_1, DCI format 1_0, and DCI format 1_1. For unicast DCI, the terminal's processing capability for DCI may be defined according to the cell granularity, but the current unicast DCI does not include MC-DCI.

In some embodiments, when MC-DCI is introduced, for MC-DCI, it is based on the cell set. The cell set granularity defines the terminal's DCI processing capability. For example, the upper limit of the terminal's DCI processing capability defined for a cell set (e.g., a set of cells that can be scheduled by MC-DCI) is 1. After the terminal processes the MC-DCI, the number of DCIs that the terminal can still process for the cell set is 1-1=0, that is, the terminal can no longer process the DCI of any cell in the cell set.

It can be seen that defining the terminal's DCI processing capability with a cell set as the granularity reduces the terminal's DCI processing capability compared to defining the terminal's DCI processing capability with a cell as the granularity. As mentioned in the previous analysis, defining the terminal's DCI processing capability with a cell set as the granularity will result in the terminal being unable to process the DCI of any cell in the cell set.

In a first aspect, an embodiment of the present disclosure proposes a capability determination method. Fig. 3 is a schematic flow chart of a capability determination method according to an embodiment of the present disclosure. The capability determination method shown in this embodiment can be executed by a terminal.

As shown in FIG3 , the capability determination method may include the following steps:

In step S301, downlink control information MC-DCI for scheduling multiple cells received in the scheduling cell is processed;

In step S302, the number of MC-DCIs processed is counted according to (per) the processing capability of the first cell for unicast downlink control information.

It should be noted that the embodiment shown in FIG. 3 may be implemented independently or in combination with at least one other embodiment in the present disclosure. The specific implementation may be selected as needed and the present disclosure is not limited thereto.

In some embodiments, the processing capability of the first cell for unicast DCI may also be referred to as the processing capability of the terminal for unicast DCI in the first cell.

According to an embodiment of the present disclosure, when MC-DCI is introduced, the terminal's processing capability for unicast DCI can be defined at the granularity of a single cell, so that after the terminal processes the MC-DCI received in the scheduling cell, the MC-DCI can be counted according to the processing capability of the first cell for unicast DCI. Since the first cell is a single cell, not a cell set, the terminal performs the operation of processing MC-DCI on the first cell, so that the first cell's processing capability for unicast DCI reaches the upper limit, and the terminal is simply unable to process the DCI of the scheduling first cell, that is, it is unable to process DCI on the first cell, but it does not affect the terminal's ability to process DCI on other cells, so it can still process DCI on other cells, thereby effectively improving the terminal's processing capability for DCI.

In some embodiments, the terminal in the embodiments of the present disclosure is a terminal that supports scheduling multiple cells through a single DCI (eg, MC-DCI).

In some embodiments, the terminal supports N1 cell sets in a physical uplink control channel (PUCCH) group. For example, N1 can be equal to 4 or other values, which is not limited in the present disclosure.

In some embodiments, the terminal supports scheduling N2 cells in a cell set through a single DCI. For example, N2 may be equal to 4 or other values, which is not limited in the present disclosure.

In the embodiments of the present disclosure, MC-DCI can be classified as unicast DCI, and unicast DCI can include not only MC-DCI but also legacy DCI, such as DCI for scheduling a single cell. Therefore, based on counting the processing of MC-DCI according to the processing capability of the first cell for unicast DCI, the processing of legacy DCI can also be counted.

For example, for the first cell, the upper limit of the DCI for scheduling downlink transmission in the processing capacity is 2. The terminal first processes an MC-DCI for scheduling downlink transmission for multiple cells in the first cell. Then it can be determined that the number of unicast DCIs that the terminal can still process in the first cell is 2-1=1. Then the terminal processes another MC-DCI for scheduling downlink transmission. If the terminal transmits traditional DCI, it can be determined that the number of unicast DCIs that can be processed by the terminal in the first cell is 1-1=0, so that the terminal can no longer process the DCI for scheduling downlink transmission in the first cell.

In some embodiments, the terminal's processing capability of unicast DCI in the first cell may include the processing capability of the first cell for unicast DCI within a unit time (also referred to as a time window), wherein the time unit includes at least one of the following: frame, subframe, time slot, symbol, and the symbol may be an OFDM (Orthogonal Frequency Division Multiplexing) symbol.

In some embodiments, the processing capability of the terminal for unicast DCI in the first cell may be determined and indicated by the network device, or may be agreed upon by a protocol, or may be determined autonomously by the terminal, or may be indicated by the network device according to the processing capability after the terminal reports its own processing capability. Wherein, in the case where the terminal autonomously determines the processing capability of the terminal for unicast DCI in the first cell, the terminal may report the processing capability of the terminal for unicast DCI in the first cell to the network device.

In some embodiments, the first cell's processing capabilities for unicast DCI may be the same or different when corresponding to a time division duplexing (TDD) carrier and when corresponding to a frequency division duplexing (FDD) carrier, and the present disclosure does not limit this.

The following embodiments mainly take the case where the first cell corresponds to an FDD carrier as an example. For example, in this case, the processing capability of the first cell for unicast DCI includes: the first upper limit value of the processing capability for DCI used to schedule uplink transmission within a unit time is 1, and the first upper limit value of the processing capability for DCI used to schedule downlink transmission within a unit time is 1.

In some embodiments, the MC-DCI includes at least one of the following:

A first MC-DCI for scheduling uplink transmission, for example, the uplink transmission includes a PUSCH (Physical Uplink Shared Channel);

The second MC-DCI is used to schedule downlink transmission, for example, the downlink transmission includes PDSCH (Physical Downlink Shared Channel).

In some embodiments, counting the number of processed MC-DCI according to the processing capability of the first cell for the unicast downlink control information includes:

Determining a first count value for a first MC-DCI count;

Determine a first difference between a first upper limit value of the DCI for scheduling uplink transmission in the processing capability of the first cell for unicast DCI and a first count value;

The method further includes: determining, based on the first difference, the number of other unicast DCIs for scheduling uplink transmission that the terminal can process in the first cell within a unit time for receiving the first MC-DCI in the scheduling cell.

For example, each time the terminal processes a first MC-DCI in the first cell, the first count value increases by 1. Here, the explanation is mainly for the first MC-DCI. In fact, each time the terminal processes a transmission DCI for scheduling uplink transmission in the first cell, the first count value also needs to increase by 1.

The processing capability of the first cell for the DCI for scheduling uplink transmission can be represented by a first upper limit value, for example, 1, then the difference between the first upper limit value and the first count value can be calculated, and the difference can represent the number of other unicast DCIs for scheduling uplink transmission processed by the terminal in the scheduling cell in the first cell within the unit time for receiving MC-DCI. For example, if the difference is 0, then the terminal can no longer process other unicast DCIs for scheduling uplink transmission in the first cell within the unit time for receiving MC-DCI in the scheduling cell; for example, if the difference is 1, then the terminal can still process one other unicast DCI for scheduling uplink transmission in the first cell within the unit time for receiving MC-DCI in the scheduling cell.

In some embodiments, counting the number of processed MC-DCI according to the processing capability of the first cell for the unicast downlink control information includes:

Determine a second count value for the second MC-DCI count;

Determine a second difference between a second upper limit value of the DCI for scheduling downlink transmission in the first cell's processing capability of unicast DCI and the second count value;

The method further includes:

The number of other unicast DCIs for scheduling downlink transmission that can be processed by the terminal in the first cell within a unit time for receiving the second MC-DCI in the scheduling cell is determined according to the second difference.

For example, each time the terminal processes a second MC-DCI in the first cell, the second count value is increased by 1. The explanation here is mainly for the second MC-DCI. In fact, when the terminal processes a transmission DCI for scheduling downlink transmission in the first cell, the second count value also needs to be increased by 1.

The processing capability of the first cell for the DCI for scheduling uplink transmission can be represented by the second upper limit value, for example, 1, then the difference between the second upper limit value and the second count value can be calculated, and the difference can represent the number of other unicast DCIs for scheduling downlink transmission processed by the terminal in the scheduling cell in the first cell within the unit time for receiving MC-DCI. For example, if the difference is 0, then the terminal can no longer process other unicast DCIs for scheduling downlink transmission in the first cell within the unit time for receiving MC-DCI in the scheduling cell; for example, if the difference is 1, then the terminal can still process one other unicast DCI for scheduling downlink transmission in the first cell within the unit time for receiving MC-DCI in the scheduling cell.

In some embodiments, the first cell includes at least one of the following:

Reference cell;

A scheduling cell, wherein when the first cell includes a scheduling cell, the scheduling cell may also be included in the scheduled cell, that is, the cell actually scheduled by the MC-DCI;

A cell among the cells that can be scheduled by MC-DCI;

The cell among the cells actually scheduled by MC-DCI.

In some embodiments, the reference cell may be determined based on a protocol agreement or indicated by a base station, and may be a cell in a cell set or a cell outside the cell set, which is not limited in the present disclosure.

For example, in some embodiments, the reference cell may be a cell with the smallest or largest identifier in a cell set; for example, in some embodiments, the reference cell may be a cell used to count the DCI size budget; for example, in some embodiments, the reference cell may be a cell used to count the blind detection parameters of MC-DCI, wherein the blind detection parameters include at least one of the following: BD (Blind Decoding), CCE (Control Channel Elements).

In some embodiments, the cells in the cells that can be scheduled by MC-DCI are agreed upon by the protocol or configured by the network device.

In some embodiments, the cells that can be scheduled by MC-DCI include at least one of the following:

The cell with the smallest index among the cells that can be scheduled by MC-DCI;

The cell with the largest index among the cells that can be scheduled by MC-DCI.

In some embodiments, the cells in the cells actually scheduled by the MC-DCI are agreed upon by the protocol or configured by the network device.

In some embodiments, the cells in the cells actually scheduled by the MC-DCI include at least one of the following:

The cell with the smallest index among the cells actually scheduled by MC-DCI;

The cell with the largest index among the cells actually scheduled by MC-DCI.

In some embodiments, the cells actually scheduled by MC-DCI can be represented in the form of a cell combination.

Taking the first cell including the reference cell as an example, for example, MC-DCI can schedule 4 cells, namely cell#2, cell#3, cell#4, and cell#5, then the cell set can be {cell#2, cell#3, cell#4, cell#5}.

For example, the terminal receives MC-DCI on the scheduling cell cell#1 (a cell outside the cell set), for example, the cells actually scheduled by MC-DCI are cell#2, cell#3, cell#4, and cell#5, specifically scheduling PDSCH. In the case where cell#2 is the reference cell, since the first upper limit value of cell#2's processing capability for DCI used to schedule downlink transmission in a unit time is 1, after the terminal processes the MC-DCI used to schedule PDSCH of multiple cells on cell#2, the terminal can no longer process the unicast DCI used to schedule downlink transmission on cell#2 in the time domain unit for receiving MC-DCI. However, the first upper limit value of the processing capability for DCI used to schedule uplink transmission in a unit time is 1, so the terminal can also process one more unicast DCI used to schedule uplink transmission on cell#2 in the time domain unit for receiving MC-DCI.

Since cell#3, cell#4, and cell#5 are not reference cells, the DCI processing capabilities of these three cells are not affected. For example, in the above-mentioned time domain unit, the terminal can still process one unicast DCI for scheduling downlink transmission and one unicast DCI for scheduling uplink transmission on cell#3; in the above-mentioned time domain unit, the terminal can still process one unicast DCI for scheduling downlink transmission and one unicast DCI for scheduling uplink transmission on cell#4; in the above-mentioned time domain unit, the terminal can still process one unicast DCI for scheduling downlink transmission and one unicast DCI for scheduling uplink transmission on cell#5.

For example, the terminal receives MC-DCI on the scheduling cell cell#2 (a cell in the cell set), for example, the cells actually scheduled by MC-DCI are cell#2, cell#3, cell#4, and cell#5, specifically scheduling PDSCH. In the case where cell#2 is the reference cell, since the first upper limit value of the processing capability of cell#2 for DCI for scheduling downlink transmission in a unit time is 1, after the terminal processes the MC-DCI for scheduling PDSCH of multiple cells on cell#2, the terminal can no longer process the unicast DCI for scheduling downlink transmission on cell#2 in the time domain unit for receiving MC-DCI. However, the first upper limit value of the processing capability for DCI for scheduling uplink transmission in a unit time is 1, so the terminal can also process one more unicast DCI for scheduling uplink transmission on cell#2 in the time domain unit for receiving MC-DCI.

Since cell#3, cell#4, and cell#5 are not reference cells, the DCI processing capabilities of these three cells are not affected. For example, in the above-mentioned time domain unit, the terminal can still process one unicast DCI for scheduling downlink transmission and one unicast DCI for scheduling uplink transmission on cell#3; in the above-mentioned time domain unit, the terminal can still process one unicast DCI for scheduling downlink transmission and one unicast DCI for scheduling uplink transmission on cell#4; in the above-mentioned time domain unit, the terminal can still process one unicast DCI for scheduling downlink transmission and one unicast DCI for scheduling uplink transmission on cell#5.

For example, the terminal receives MC-DCI on the scheduling cell cell#2. For example, the cells actually scheduled by MC-DCI are cell#2, cell#3, cell#4, and cell#5, specifically scheduling PDSCH. In the case where cell#3 is the reference cell, since the first upper limit value of cell#3's processing capability for DCI used to schedule downlink transmission in a unit time is 1, after the terminal processes the MC-DCI used to schedule PDSCH of multiple cells on cell#3, the terminal can no longer process the unicast DCI used to schedule downlink transmission on cell#3 in the time domain unit for receiving MC-DCI. However, the first upper limit value of the processing capability for DCI used to schedule uplink transmission in a unit time is 1, so the terminal can also process one more unicast DCI used to schedule uplink transmission on cell#3 in the time domain unit for receiving MC-DCI.

Since cell#2, cell#4, and cell#5 are not reference cells, the DCI processing capabilities of these three cells are not affected. For example, in the above time domain unit, the terminal can still process one unicast DCI for scheduling downlink transmission and one unicast DCI for scheduling uplink transmission on cell#2; in the above time domain unit, the terminal can still process one unicast DCI for scheduling downlink transmission and one unicast DCI for scheduling uplink transmission on cell#4; in the above time domain unit, the terminal can still process one unicast DCI for scheduling downlink transmission and one unicast DCI for scheduling uplink transmission on cell#5.

Taking the first cell including the scheduling cell as an example, for example, MC-DCI can schedule 4 cells, namely cell#2, cell#3, cell#4, and cell#5, then the cell set can be {cell#2, cell#3, cell#4, cell#5}.

For example, the terminal receives MC-DCI on the scheduling cell cell#1. For example, the cells actually scheduled by MC-DCI are cell#2, cell#3, cell#4, and cell#5, specifically scheduling PDSCH. Since the first upper limit value of cell#1's processing capability for DCI used to schedule downlink transmission in a unit time is 1, after the terminal processes the MC-DCI used to schedule PDSCH of multiple cells on cell#1, the terminal can no longer process the unicast DCI used to schedule downlink transmission on cell#1 in the time domain unit for receiving MC-DCI. However, the first upper limit value of the processing capability for DCI used to schedule uplink transmission in a unit time is 1, so the terminal can also process one more unicast DCI used to schedule uplink transmission on cell#1 in the time domain unit for receiving MC-DCI.

Since cell#2, cell#3, cell#4, and cell#5 are not scheduling cells, the DCI processing capabilities of these three cells are not affected. For example, in the above-mentioned time domain unit, the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on cell#3; in the above-mentioned time domain unit, the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on cell#4; in the above-mentioned time domain unit, the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on cell#5.

For example, the terminal receives MC-DCI on the scheduling cell cell#2. For example, the cells actually scheduled by MC-DCI are cell#2, cell#3, cell#4, and cell#5, specifically scheduling PDSCH. Since the first upper limit value of cell#2's processing capability for DCI used to schedule downlink transmission in a unit time is 1, after the terminal processes the MC-DCI used to schedule PDSCH of multiple cells on cell#2, the terminal can no longer process unicast DCI used to schedule downlink transmission on cell#2 in the time domain unit for receiving MC-DCI. However, the first upper limit value of the processing capability for DCI used to schedule uplink transmission in a unit time is 1, so the terminal can also process one more unicast DCI used to schedule uplink transmission on cell#2 in the time domain unit for receiving MC-DCI.

Since cell#3, cell#4, and cell#5 are not scheduling cells, the DCI processing capabilities of these three cells are not affected. For example, in the above time domain unit, the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on cell#3; in the above time domain unit, the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on cell#4; in the above time domain unit, the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on cell#5.

For example, the terminal receives MC-DCI on the scheduling cell cell#2. For example, the cells actually scheduled by MC-DCI are cell#3, cell#4, and cell#5, specifically scheduling PDSCH. In the case where cell#3 is the reference cell, since the first upper limit value of cell#3's processing capability for DCI used to schedule downlink transmission in a unit time is 1, after the terminal processes the MC-DCI used to schedule PDSCH of multiple cells on cell#3, the terminal can no longer process the unicast DCI used to schedule downlink transmission on cell#3 in the time domain unit for receiving MC-DCI. However, the first upper limit value of the processing capability for DCI used to schedule uplink transmission in a unit time is 1, so the terminal can also process one more unicast DCI used to schedule uplink transmission on cell#3 in the time domain unit for receiving MC-DCI.

Since cell#3, cell#4, and cell#5 are not scheduling cells, the processing capabilities of these three cells for DCI are not affected. For example, in the above time domain unit, the terminal can still process one DCI for scheduling downlink on cell#2. The terminal can process one unicast DCI for scheduling downlink transmission and one unicast DCI for scheduling uplink transmission on cell#4 in the above time domain unit; the terminal can still process one unicast DCI for scheduling downlink transmission and one unicast DCI for scheduling uplink transmission on cell#5 in the above time domain unit.

Taking the first cell including the cells that can be scheduled by MC-DCI as an example, for example, it can be the cell with the smallest index or the largest index among the cells that can be scheduled by MC-DCI. For example, MC-DCI can schedule 4 cells, namely cell#2, cell#3, cell#4, and cell#5, then the cell set can be {cell#2, cell#3, cell#4, cell#5}. Taking the first cell including the cell with the smallest index among the cells that can be scheduled by MC-DCI, that is, cell#2, as an example.

For example, the terminal receives MC-DCI on the scheduling cell cell#1. For example, the cells actually scheduled by MC-DCI are cell#2, cell#3, cell#4, and cell#5, specifically scheduling PDSCH. When the first cell is cell#2, since the first upper limit value of cell#2's processing capability for DCI used to schedule downlink transmission in a unit time is 1, after the terminal processes the MC-DCI used to schedule PDSCH of multiple cells on cell#2, the terminal can no longer process the unicast DCI used to schedule downlink transmission on cell#2 in the time domain unit for receiving MC-DCI. However, the first upper limit value of the processing capability for DCI used to schedule uplink transmission in a unit time is 1, so the terminal can also process one more unicast DCI used to schedule uplink transmission on cell#2 in the time domain unit for receiving MC-DCI.

Since cell#3, cell#4, and cell#5 are not the first cells, the DCI processing capabilities of these three cells are not affected. For example, in the above-mentioned time domain unit, the terminal can still process one unicast DCI for scheduling downlink transmission and one unicast DCI for scheduling uplink transmission on cell#3; in the above-mentioned time domain unit, the terminal can still process one unicast DCI for scheduling downlink transmission and one unicast DCI for scheduling uplink transmission on cell#4; in the above-mentioned time domain unit, the terminal can still process one unicast DCI for scheduling downlink transmission and one unicast DCI for scheduling uplink transmission on cell#5.

For example, the terminal receives MC-DCI on the scheduling cell cell#2. For example, the cells actually scheduled by MC-DCI are cell#2, cell#3, cell#4, and cell#5, specifically scheduling PDSCH. When the first cell is cell#2, since the first upper limit of the processing capability of cell#2 for DCI for scheduling downlink transmission in a unit time is 1, after the terminal processes the MC-DCI for scheduling PDSCH of multiple cells on cell#2, the terminal can no longer process the unicast DCI for scheduling downlink transmission on cell#2 in the time domain unit for receiving MC-DCI. However, the first upper limit of the processing capability for DCI for scheduling uplink transmission in a unit time is 1, so the terminal can also process one more unicast DCI for scheduling uplink transmission on cell#2 in the time domain unit for receiving MC-DCI.

Since cell#3, cell#4, and cell#5 are not the first cells, the DCI processing capabilities of these three cells are not affected. For example, in the above-mentioned time domain unit, the terminal can still process one unicast DCI for scheduling downlink transmission and one unicast DCI for scheduling uplink transmission on cell#3; in the above-mentioned time domain unit, the terminal can still process one unicast DCI for scheduling downlink transmission and one unicast DCI for scheduling uplink transmission on cell#4; in the above-mentioned time domain unit, the terminal can still process one unicast DCI for scheduling downlink transmission and one unicast DCI for scheduling uplink transmission on cell#5.

For example, the terminal receives MC-DCI on the scheduling cell cell#2. For example, the cells actually scheduled by MC-DCI are cell#3, cell#4, and cell#5, specifically scheduling PDSCH. When the first cell is cell#2, since the first upper limit value of cell#2's processing capability for DCI used to schedule downlink transmission in a unit time is 1, after the terminal processes the MC-DCI used to schedule PDSCH of multiple cells on cell#2, the terminal can no longer process the unicast DCI used to schedule downlink transmission on cell#2 in the time domain unit for receiving MC-DCI. However, the first upper limit value of the processing capability for DCI used to schedule uplink transmission in a unit time is 1, so the terminal can also process one more unicast DCI used to schedule uplink transmission on cell#2 in the time domain unit for receiving MC-DCI.

Since cell#3, cell#4, and cell#5 are not the first cells, the processing capabilities of these three cells for DCI For example, in the above time domain unit, the terminal can still process one unicast DCI for scheduling downlink transmission and one unicast DCI for scheduling uplink transmission on cell#3; in the above time domain unit, the terminal can still process one unicast DCI for scheduling downlink transmission and one unicast DCI for scheduling uplink transmission on cell#4; in the above time domain unit, the terminal can still process one unicast DCI for scheduling downlink transmission and one unicast DCI for scheduling uplink transmission on cell#5.

Taking the first cell including the cell in the cell actually scheduled by MC-DCI as an example, for example, it can be the cell with the smallest index or the largest index in the cell actually scheduled by MC-DCI. For example, MC-DCI can schedule 4 cells, namely cell#2, cell#3, cell#4, and cell#5, then the cell set can be {cell#2, cell#3, cell#4, cell#5}, and the cell actually scheduled can be one or more cells in the cell set. Taking the first cell including the cell with the smallest index in the cell actually scheduled by MC-DCI as an example.

For example, the terminal receives MC-DCI on the scheduling cell cell#1 (a cell outside the cell set), for example, the cells actually scheduled by MC-DCI are cell#2, cell#3, cell#4, and cell#5, specifically scheduling PDSCH. Among them, cell#2 has the smallest index, so cell#2 is used as the first cell. Since the first upper limit value of cell#2's processing capability for DCI used to schedule downlink transmission in a unit time is 1, after the terminal processes the MC-DCI for scheduling PDSCH of multiple cells on cell#2, the terminal can no longer process the unicast DCI used to schedule downlink transmission on cell#2 in the time domain unit receiving MC-DCI. However, the first upper limit value of the processing capability for DCI used to schedule uplink transmission in a unit time is 1, so the terminal can also process one more unicast DCI used to schedule uplink transmission on cell#2 in the time domain unit receiving MC-DCI.

Since cell#3, cell#4, and cell#5 are not the first cells, the DCI processing capabilities of these three cells are not affected. For example, in the above-mentioned time domain unit, the terminal can still process one unicast DCI for scheduling downlink transmission and one unicast DCI for scheduling uplink transmission on cell#3; in the above-mentioned time domain unit, the terminal can still process one unicast DCI for scheduling downlink transmission and one unicast DCI for scheduling uplink transmission on cell#4; in the above-mentioned time domain unit, the terminal can still process one unicast DCI for scheduling downlink transmission and one unicast DCI for scheduling uplink transmission on cell#5.

For example, the terminal receives MC-DCI on the scheduling cell cell#2 (a cell in the cell set), and the cells actually scheduled by MC-DCI are cell#3, cell#4, and cell#5, specifically scheduling PDSCH. Among them, cell#3 has the smallest index, so cell#3 is used as the first cell. Since the first upper limit value of the processing capability of cell#3 for DCI used for scheduling downlink transmission in a unit time is 1, after the terminal processes the MC-DCI for scheduling PDSCH of multiple cells on cell#3, the terminal can no longer process the unicast DCI for scheduling downlink transmission on cell#3 in the time domain unit of receiving MC-DCI. However, the first upper limit value of the processing capability for DCI used for scheduling uplink transmission in a unit time is 1, so the terminal can also process one more unicast DCI for scheduling uplink transmission on cell#3 in the time domain unit of receiving MC-DCI.

Since cell#2, cell#4, and cell#5 are not the first cells, the DCI processing capabilities of these three cells are not affected. For example, in the above time domain unit, the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on cell#2; in the above time domain unit, the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on cell#4; in the above time domain unit, the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on cell#5.

For example, the terminal receives MC-DCI on the scheduling cell cell#2. For example, the cells actually scheduled by MC-DCI are cell#4 and cell#5, specifically scheduling PDSCH. Among them, cell#4 has the smallest index, so cell#4 is used as the first cell. Since the first upper limit of cell#4's processing capability for DCI used to schedule downlink transmission in a unit time is 1, after the terminal processes the MC-DCI used to schedule PDSCH of multiple cells on cell#4, the terminal can no longer process the unicast DCI used to schedule downlink transmission on cell#4 in the time domain unit receiving MC-DCI. But The first upper limit value of the processing capability of DCI for scheduling uplink transmission in unit time is 1, so the terminal can process one more unicast DCI for scheduling uplink transmission on cell#4 in the time domain unit for receiving MC-DCI.

Since cell#2, cell#3, and cell#5 are not reference cells, the DCI processing capabilities of these three cells are not affected. For example, in the above-mentioned time domain unit, the terminal can still process one unicast DCI for scheduling downlink transmission and one unicast DCI for scheduling uplink transmission on cell#2; in the above-mentioned time domain unit, the terminal can still process one unicast DCI for scheduling downlink transmission and one unicast DCI for scheduling uplink transmission on cell#3; in the above-mentioned time domain unit, the terminal can still process one unicast DCI for scheduling downlink transmission and one unicast DCI for scheduling uplink transmission on cell#5.

In a second aspect, an embodiment of the present disclosure proposes a capability determination method. Fig. 4 is a schematic flow chart of a capability determination method according to an embodiment of the present disclosure. The capability determination method shown in this embodiment can be executed by a network device.

As shown in FIG4 , the capability determination method may include the following steps:

In step S401, downlink control information MC-DCI for scheduling multiple cells is sent to the terminal in the scheduling cell;

In step S402, the MC-DCI processed by the terminal is counted according to the processing capability of the first cell for unicast downlink control information.

According to an embodiment of the present disclosure, when MC-DCI is introduced, the terminal's processing capability for unicast DCI can be defined at the granularity of a single cell, so that after the network device sends MC-DCI to the terminal in the scheduling cell, the terminal can process the MC-DCI, and the network device can count the MC-DCI according to the processing capability of the first cell for unicast DCI. Since the first cell is a single cell, not a collection of cells, even if the network device determines that the terminal performs an operation of processing MC-DCI in the first cell, so that the first cell's processing capability for unicast DCI reaches the upper limit, it only determines that the terminal can no longer process the DCI of the first cell, that is, the terminal can no longer process DCI in the first cell, but it does not affect the terminal's ability to process DCI in other cells, so it can still be determined that the terminal can process DCI in other cells, thereby effectively improving the terminal's processing capability for DCI.

On this basis, in some embodiments, the network device can configure the terminal as needed, and the terminal's processing capability of unicast DCI in the first cell and other cells can be considered during the configuration process to avoid configuring the terminal beyond its processing capability of unicast DCI in the first cell and other cells.

In some embodiments, the terminal supports N1 cell sets in a physical uplink control channel (PUCCH) group. For example, N1 can be equal to 4 or other values, which is not limited in the present disclosure.

In some embodiments, the terminal supports scheduling N2 cells in a cell set through a single DCI. For example, N2 may be equal to 4 or other values, which is not limited in the present disclosure.

In the embodiments of the present disclosure, MC-DCI can be classified as unicast DCI, and unicast DCI can include not only MC-DCI but also legacy DCI, such as DCI for scheduling a single cell. Therefore, based on counting the processing of MC-DCI according to the processing capability of the first cell for unicast DCI, the processing of legacy DCI can also be counted.

For example, for the first cell, the upper limit of the DCI for scheduling downlink transmission in the processing capability is 2. The terminal first processes an MC-DCI for scheduling downlink transmission for multiple cells in the first cell. Then it can be determined that the number of unicast DCIs that the terminal can still process in the first cell is 2-1=1. Then the terminal processes a traditional DCI for scheduling downlink transmission. Then it can be determined that the number of unicast DCIs that the terminal can still process in the first cell is 1-1=0. As a result, the terminal can no longer process the DCI for scheduling downlink transmission in the first cell.

In some embodiments, the terminal's processing capability of unicast DCI in the first cell may include the first cell's processing capability of unicast DCI within a unit time (also referred to as a time window), wherein the time unit includes at least one of the following: frame, subframe, time slot, symbol, and the symbol may be an OFDM symbol.

In some embodiments, the processing capability of the terminal for unicast DCI in the first cell may be determined and indicated by the network device, or may be agreed upon by a protocol, or may be determined autonomously by the terminal, or may be indicated by the network device according to the processing capability after the terminal reports its own processing capability. Wherein, in the case where the terminal autonomously determines the processing capability of the terminal for unicast DCI in the first cell, the terminal may report the processing capability of the terminal for unicast DCI in the first cell to the network device.

In some embodiments, the first cell may have the same or different processing capabilities for unicast DCI when corresponding to a time division duplex (TDD) carrier and when corresponding to a frequency division duplex (FDD) carrier, and the present disclosure is not limited in this regard.

The following embodiments mainly take the case where the first cell corresponds to an FDD carrier as an example. For example, in this case, the processing capability of the first cell for unicast DCI includes: the first upper limit value of the processing capability for DCI used to schedule uplink transmission within a unit time is 1, and the first upper limit value of the processing capability for DCI used to schedule downlink transmission within a unit time is 1.

In some embodiments, the MC-DCI includes at least one of the following:

A first MC-DCI for scheduling uplink transmission, for example, the uplink transmission includes a PUSCH;

The second MC-DCI is used for scheduling downlink transmission, for example, the downlink transmission includes PDSCH.

In some embodiments, counting the number of MC-DCIs processed by the terminal according to the processing capability of the first cell for unicast downlink control information includes:

Determine a first count value for counting a first MC-DCI processed by a terminal;

Determine a first difference between a first upper limit value of the DCI for scheduling uplink transmission in the processing capability of the first cell for unicast DCI and a first count value;

The method further includes: determining, based on the first difference, the number of other unicast DCIs for scheduling uplink transmission that the terminal can process in the first cell within a unit time for receiving the first MC-DCI in the scheduling cell.

For example, each time the terminal processes a first MC-DCI in the first cell, the first count value increases by 1. Here, the explanation is mainly for the first MC-DCI. In fact, each time the terminal processes a transmission DCI for scheduling uplink transmission in the first cell, the first count value also needs to increase by 1.

The processing capability of the first cell for the DCI for scheduling uplink transmission can be represented by a first upper limit value, for example, 1, then the difference between the first upper limit value and the first count value can be calculated, and the difference can represent the number of other unicast DCIs for scheduling uplink transmission processed by the terminal in the first cell within the unit time for receiving MC-DCI in the scheduling cell. For example, if the difference is 0, the network device can determine that in the scheduling cell, within the unit time for receiving MC-DCI, the terminal can no longer process other unicast DCIs for scheduling uplink transmission in the first cell; for example, if the difference is 1, the network device can determine that in the scheduling cell, within the unit time for receiving MC-DCI, the terminal can still process one other unicast DCI for scheduling uplink transmission in the first cell.

In some embodiments, counting the number of MC-DCIs processed by the terminal according to the processing capability of the first cell for unicast downlink control information includes:

Determine a second count value for counting a second MC-DCI processed by the terminal;

Determine a second upper limit value of the DCI for scheduling downlink transmission in the first cell's processing capability for unicast DCI a second difference with a second count value;

The method further includes: determining, based on the second difference, the number of other unicast DCIs for scheduling downlink transmission that the terminal can process in the first cell within a unit time for receiving the second MC-DCI in the scheduling cell.

For example, each time the terminal processes a second MC-DCI in the first cell, the second count value is increased by 1. The explanation here is mainly for the second MC-DCI. In fact, when the terminal processes a transmission DCI for scheduling downlink transmission in the first cell, the second count value also needs to be increased by 1.

The processing capability of the first cell for the DCI for scheduling uplink transmission can be represented by a second upper limit value, for example, 1, then the difference between the second upper limit value and the second count value can be calculated, and the difference can represent the number of other unicast DCIs for scheduling downlink transmission that the terminal processes in the first cell within the unit time for receiving MC-DCI in the scheduling cell. For example, if the difference is 0, the network device can determine that in the scheduling cell, within the unit time for receiving MC-DCI, the terminal can no longer process other unicast DCIs for scheduling downlink transmission in the first cell; for example, if the difference is 1, the network device can determine that in the scheduling cell, within the unit time for receiving MC-DCI, the terminal can still process one other unicast DCI for scheduling downlink transmission in the first cell.

In some embodiments, the first cell includes at least one of the following:

Reference cell;

A scheduling cell, wherein when the first cell includes a scheduling cell, the scheduling cell may also be included in the scheduled cell, that is, the cell actually scheduled by the MC-DCI;

A cell among the cells that can be scheduled by MC-DCI;

The cell among the cells actually scheduled by MC-DCI.

In some embodiments, the reference cell may be determined based on a protocol agreement or indicated by a base station, and may be a cell in a cell set or a cell outside the cell set, which is not limited in the present disclosure.

For example, in some embodiments, the reference cell may be a cell with the smallest or largest identifier in a cell set; for example, in some embodiments, the reference cell may be a cell used to count the DCI size budget; for example, in some embodiments, the reference cell may be a cell used to count the blind detection parameters of MC-DCI, wherein the blind detection parameters include at least one of the following: BD, CCE.

In some embodiments, the cells in the cells that can be scheduled by MC-DCI are agreed upon by the protocol or configured by the network device.

In some embodiments, the cells that can be scheduled by MC-DCI include at least one of the following:

The cell with the smallest index among the cells that can be scheduled by MC-DCI;

The cell with the largest index among the cells that can be scheduled by MC-DCI.

In some embodiments, the cells in the cells actually scheduled by the MC-DCI are agreed upon by the protocol or configured by the network device.

In some embodiments, the cells in the cells actually scheduled by the MC-DCI include at least one of the following:

The cell with the smallest index among the cells actually scheduled by MC-DCI;

The cell with the largest index among the cells actually scheduled by MC-DCI.

In some embodiments, the cells actually scheduled by MC-DCI can be represented in the form of a cell combination.

Taking the first cell including the reference cell as an example, for example, MC-DCI can schedule four cells, namely cell#2, cell#3, cell#4, cell#5, then the cell set can be {cell#2, cell#3, cell#4, cell#5}.

For example, the network device sends MC-DCI to the terminal on the scheduling cell cell#1. For example, the cells actually scheduled by MC-DCI are cell#2, cell#3, cell#4, and cell#5, specifically scheduling PDSCH. In the case where cell#2 is the reference cell, since the first upper limit value of cell#2's processing capability for DCI used to schedule downlink transmission in a unit time is 1, the network device determines that after the terminal processes the MC-DCI for scheduling PDSCH of multiple cells on cell#2, it can no longer process the unicast DCI for scheduling downlink transmission on cell#2 in the time domain unit for receiving MC-DCI. However, the first upper limit value of the processing capability for DCI used to schedule uplink transmission in a unit time is 1, so the network device can determine that the terminal can also process one more unicast DCI for scheduling uplink transmission on cell#2 in the time domain unit for receiving MC-DCI.

Since cell#3, cell#4, and cell#5 are not reference cells, the DCI processing capabilities of these three cells are not affected. For example, the network device can determine that the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on cell#3 in the above time domain unit; and determine that the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on cell#4 in the above time domain unit; and determine that the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on cell#5 in the above time domain unit.

For example, the network device sends MC-DCI to the terminal on the scheduling cell cell#2. For example, the cells actually scheduled by MC-DCI are cell#2, cell#3, cell#4, and cell#5, specifically scheduling PDSCH. In the case where cell#2 is the reference cell, since the first upper limit value of cell#2's processing capability for DCI used to schedule downlink transmission in a unit time is 1, the network device determines that after the terminal processes the MC-DCI used to schedule PDSCH of multiple cells on cell#2, it can no longer process the unicast DCI used to schedule downlink transmission on cell#2 in the time domain unit for receiving MC-DCI. However, the first upper limit value of the processing capability for DCI used to schedule uplink transmission in a unit time is 1, so the network device can determine that the terminal can also process one more unicast DCI used to schedule uplink transmission on cell#2 in the time domain unit for receiving MC-DCI.

Since cell#3, cell#4, and cell#5 are not reference cells, the DCI processing capabilities of these three cells are not affected. For example, the network device can determine that the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on cell#3 in the above time domain unit; and determine that the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on cell#4 in the above time domain unit; and determine that the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on cell#5 in the above time domain unit.

For example, the network device sends MC-DCI to the terminal on the scheduling cell cell#2. For example, the cells actually scheduled by MC-DCI are cell#2, cell#3, cell#4, and cell#5, specifically scheduling PDSCH. In the case where cell#3 is the reference cell, since the first upper limit value of cell#3's processing capability for DCI used to schedule downlink transmission in a unit time is 1, the network device determines that after the terminal processes the MC-DCI used to schedule PDSCH of multiple cells on cell#3, it can no longer process the unicast DCI used to schedule downlink transmission on cell#3 in the time domain unit for receiving MC-DCI. However, the first upper limit value of the processing capability for DCI used to schedule uplink transmission in a unit time is 1, so the network device can determine that the terminal can also process one more unicast DCI used to schedule uplink transmission on cell#3 in the time domain unit for receiving MC-DCI.

Since cell#2, cell#4, and cell#5 are not reference cells, the DCI processing capabilities of these three cells are not affected. For example, the network device can determine that the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on cell#2 in the above time domain unit; and determine that the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on cell#4 in the above time domain unit; and determine that the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on cell#5 in the above time domain unit.

Taking the first cell including the scheduling cell as an example, for example, MC-DCI can schedule 4 cells, namely cell#2, cell#3, cell#4, and cell#5, then the cell set can be {cell#2, cell#3, cell#4, cell#5}.

For example, the network device sends MC-DCI to the terminal on the scheduling cell cell#1. For example, the cells actually scheduled by MC-DCI are cell#2, cell#3, cell#4, and cell#5, specifically scheduling PDSCH. Since the first upper limit of the processing capacity of cell#1 for DCI used to schedule downlink transmission in a unit time is 1, the network device determines that after the terminal processes the MC-DCI used to schedule PDSCH of multiple cells on cell#1, it can no longer process the unicast DCI used to schedule downlink transmission on cell#1 in the time domain unit for receiving MC-DCI. However, the first upper limit of the processing capacity for DCI used to schedule uplink transmission in a unit time is 1, so the network device can determine that the terminal can also process one more unicast DCI used to schedule uplink transmission on cell#1 in the time domain unit for receiving MC-DCI.

Since cell#2, cell#3, cell#4, and cell#5 are not scheduling cells, the DCI processing capabilities of these three cells are not affected. For example, the network device can determine that the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on cell#3 in the above time domain unit; and determine that the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on cell#4 in the above time domain unit; and determine that the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on cell#5 in the above time domain unit.

For example, the network device sends MC-DCI to the terminal on the scheduling cell cell#2. For example, the cells actually scheduled by MC-DCI are cell#2, cell#3, cell#4, and cell#5, specifically scheduling PDSCH. Since the first upper limit of the processing capacity of cell#2 for DCI used to schedule downlink transmission in a unit time is 1, the network device determines that after the terminal processes the MC-DCI used to schedule PDSCH of multiple cells on cell#2, it can no longer process the unicast DCI used to schedule downlink transmission on cell#2 in the time domain unit for receiving MC-DCI. However, the first upper limit of the processing capacity for DCI used to schedule uplink transmission in a unit time is 1, so the network device can determine that the terminal can also process one more unicast DCI used to schedule uplink transmission on cell#2 in the time domain unit for receiving MC-DCI.

Since cell#3, cell#4, and cell#5 are not scheduling cells, the DCI processing capabilities of these three cells are not affected. For example, the network device can determine that the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission in cell#3 in the above time domain unit; and determine that the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission in cell#4 in the above time domain unit; and determine that the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission in cell#5 in the above time domain unit.

For example, the network device sends MC-DCI to the terminal on the scheduling cell cell#2. For example, the cells actually scheduled by MC-DCI are cell#3, cell#4, and cell#5, specifically scheduling PDSCH. In the case where cell#3 is the reference cell, since the first upper limit value of cell#3's processing capability for DCI used to schedule downlink transmission in a unit time is 1, the network device determines that after the terminal processes the MC-DCI used to schedule PDSCH of multiple cells on cell#3, it can no longer process the unicast DCI used to schedule downlink transmission on cell#3 in the time domain unit for receiving MC-DCI. However, the first upper limit value of the processing capability for DCI used to schedule uplink transmission in a unit time is 1, so the network device can determine that the terminal can also process one more unicast DCI used to schedule uplink transmission on cell#3 in the time domain unit for receiving MC-DCI.

Since cell#3, cell#4, and cell#5 are not scheduling cells, the DCI processing capabilities of these three cells are not affected. For example, the network device can determine that the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on cell#2 in the above time domain unit; and determine that the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on cell#4 in the above time domain unit; and determine that the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on cell#5 in the above time domain unit.

Taking the first cell including the cells that can be scheduled by MC-DCI as an example, for example, it can be the cell with the smallest index or the largest index among the cells that can be scheduled by MC-DCI. For example, MC-DCI can schedule 4 cells, namely cell#2, cell#3, cell#4, and cell#5, then the cell set can be {cell#2, cell#3, cell#4, cell#5}. Taking the first cell including the cell with the smallest index among the cells that can be scheduled by MC-DCI, that is, cell#2, as an example.

For example, the network device sends MC-DCI to the terminal on the scheduling cell cell#1. For example, the cells actually scheduled by MC-DCI are cell#2, cell#3, cell#4, and cell#5, specifically scheduling PDSCH. In the case where the first cell is cell#2, since the first upper limit value of cell#2's processing capacity for DCI for scheduling downlink transmission in a unit time is 1, the network device determines that after the terminal processes the MC-DCI for scheduling PDSCH of multiple cells on cell#2, it can no longer process the unicast DCI for scheduling downlink transmission on cell#2 in the time domain unit for receiving MC-DCI. However, the first upper limit value of the processing capacity for DCI for scheduling uplink transmission in a unit time is 1, so the network device can determine that the terminal can also process one more unicast DCI for scheduling uplink transmission on cell#2 in the time domain unit for receiving MC-DCI.

Since cell#3, cell#4, and cell#5 are not the first cells, the DCI processing capabilities of these three cells are not affected. For example, the network device can determine that the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on cell#3 in the above time domain unit; and determine that the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on cell#4 in the above time domain unit; and determine that the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on cell#5 in the above time domain unit.

For example, the network device sends MC-DCI to the terminal on the scheduling cell cell#2. For example, the cells actually scheduled by MC-DCI are cell#2, cell#3, cell#4, and cell#5, specifically scheduling PDSCH. In the case where the first cell is cell#2, since the first upper limit value of cell#2's processing capability for DCI for scheduling downlink transmission in a unit time is 1, after the network device determines that the terminal has processed the MC-DCI for scheduling PDSCH of multiple cells on cell#2, the terminal can no longer process the unicast DCI for scheduling downlink transmission on cell#2 in the time domain unit receiving MC-DCI. However, the first upper limit value of the processing capability for DCI for scheduling uplink transmission in a unit time is 1, so the network device can determine that the terminal can also process one more unicast DCI for scheduling uplink transmission on cell#2 in the time domain unit receiving MC-DCI.

Since cell#3, cell#4, and cell#5 are not the first cells, the DCI processing capabilities of these three cells are not affected. For example, the network device can determine that the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on cell#3 in the above time domain unit; and determine that the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on cell#4 in the above time domain unit; and determine that the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on cell#5 in the above time domain unit.

For example, the network device sends MC-DCI to the terminal on the scheduling cell cell#2. For example, the cells actually scheduled by MC-DCI are cell#3, cell#4, and cell#5, specifically scheduling PDSCH. When the first cell is cell#2, since the first upper limit value of cell#2's processing capacity for DCI used to schedule downlink transmission in a unit time is 1, the network device determines that after the terminal processes the MC-DCI used to schedule PDSCH of multiple cells on cell#2, it can no longer process the unicast DCI used to schedule downlink transmission on cell#2 in the time domain unit for receiving MC-DCI. However, the first upper limit value of the processing capacity for DCI used to schedule uplink transmission in a unit time is 1, so the network device can determine that the terminal can also process one more unicast DCI used to schedule uplink transmission on cell#2 in the time domain unit for receiving MC-DCI.

Since cell#3, cell#4, and cell#5 are not the first cells, the processing capabilities of these three cells for DCI are not affected. For example, the network device can determine that the terminal is in the above time domain unit and can still process 1 on cell#3. The method comprises the following steps: determining a unicast DCI for scheduling downlink transmission and a unicast DCI for scheduling uplink transmission in the time domain unit; determining that the terminal can still process, in cell#4, one unicast DCI for scheduling downlink transmission and one unicast DCI for scheduling uplink transmission in the time domain unit; and determining that the terminal can still process, in cell#5, one unicast DCI for scheduling downlink transmission and one unicast DCI for scheduling uplink transmission in the time domain unit.

Taking the first cell including the cell in the cell actually scheduled by MC-DCI as an example, for example, it can be the cell with the smallest index or the largest index in the cell actually scheduled by MC-DCI. For example, MC-DCI can schedule 4 cells, namely cell#2, cell#3, cell#4, and cell#5, then the cell set can be {cell#2, cell#3, cell#4, cell#5}, and the cell actually scheduled can be one or more cells in the cell set. Taking the first cell including the cell with the smallest index in the cell actually scheduled by MC-DCI as an example.

For example, the network device sends MC-DCI to the terminal on the scheduling cell cell#1. For example, the cells actually scheduled by MC-DCI are cell#2, cell#3, cell#4, and cell#5, specifically scheduling PDSCH. Among them, cell#2 has the smallest index, so cell#2 is used as the first cell. Since the first upper limit value of cell#2's processing capacity for DCI used to schedule downlink transmission in a unit time is 1, the network device determines that after the terminal processes the MC-DCI for scheduling PDSCH of multiple cells on cell#2, it can no longer process the unicast DCI for scheduling downlink transmission on cell#2 in the time domain unit receiving MC-DCI. However, the first upper limit value of the processing capacity for DCI used to schedule uplink transmission in a unit time is 1, so the network device can determine that the terminal can also process another unicast DCI for scheduling uplink transmission on cell#2 in the time domain unit receiving MC-DCI.

Since cell#3, cell#4, and cell#5 are not the first cells, the DCI processing capabilities of these three cells are not affected. For example, the network device can determine that the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on cell#3 in the above time domain unit; and determine that the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on cell#4 in the above time domain unit; and determine that the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on cell#5 in the above time domain unit.

For example, the network device sends MC-DCI to the terminal on the scheduling cell cell#2. For example, the cells actually scheduled by MC-DCI are cell#3, cell#4, and cell#5, specifically scheduling PDSCH. Among them, cell#3 has the smallest index, so cell#3 is used as the first cell. Since the first upper limit value of cell#3's processing capacity for DCI used to schedule downlink transmission in a unit time is 1, after the network device determines that the terminal has processed the MC-DCI used to schedule PDSCH of multiple cells on cell#3, the terminal can no longer process the unicast DCI used to schedule downlink transmission on cell#3 in the time domain unit receiving MC-DCI. However, the first upper limit value of the processing capacity for DCI used to schedule uplink transmission in a unit time is 1, so the network device can determine that the terminal can also process another unicast DCI used to schedule uplink transmission on cell#3 in the time domain unit receiving MC-DCI.

Since cell#2, cell#4, and cell#5 are not the first cells, the DCI processing capabilities of these three cells are not affected. For example, the network device can determine that the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on cell#2 in the above time domain unit; and determine that the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on cell#4 in the above time domain unit; and determine that the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on cell#5 in the above time domain unit.

For example, the network device sends MC-DCI to the terminal on the scheduling cell cell#2. For example, the cells actually scheduled by MC-DCI are cell#4 and cell#5, specifically scheduling PDSCH. Among them, cell#4 has the smallest index, so cell#4 is used as the first cell. Since the first upper limit of cell#4's processing capacity for DCI used to schedule downlink transmission in a unit time is 1, after the terminal processes the MC-DCI for scheduling PDSCH of multiple cells on cell#4, the network device determines that the terminal can no longer process the unicast DCI used to schedule downlink transmission on cell#4 in the time domain unit receiving MC-DCI. However, the first upper limit of the processing capacity for DCI used to schedule uplink transmission in a unit time is The limit value is 1, so the network device can determine that the terminal is in the time domain unit for receiving MC-DCI, and can also process one more unicast DCI for scheduling uplink transmission on cell#4.

Since cell#2, cell#3, and cell#5 are not reference cells, the DCI processing capabilities of these three cells are not affected. For example, the network device can determine that the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on cell#2 in the above time domain unit; and determine that the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on cell#3 in the above time domain unit; and determine that the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on cell#5 in the above time domain unit.
